This doesn't really belong in Mailman, it's more of an email
(the module) problem. I've sent in a bugreport to the
appropriate place, leaving this patch and the bug open until
it's fixed. (If it is; if it isn't, we need to wrap
get_payload in the appropriate try/except, which might be a
good idea anyway.)
